A media resource locator (MRL) is a string of characters used to identify a multimedia resource or part of a multimedia resource. A MRL may be used to identify inputs or outputs to VLC media player.

The MRL syntax is:

[[access][/demux]://]URL[#[title][:chapter][-[title][:chapter]]] [:option=value ...]

(in earlier versions of VLC, the delimiter before the optional title and chapter was '@', not '#'.)

Exception

An exception to these rules appears to be with UDP/RTP streams, where it may look like:

udp://@:portnumber
# Example: 
#   udp://@:1234
#
# Apparently the @ has a meaning like localhost, though
#   udp://localhost:1234
# doesn't seem to work in this circumstance, for some reason.
